Datasheet
## **POLYSWITCH RESETTABLE DEVICES** Line-Voltage-Rated Devices PolySwitch line-voltage-rated (LVR) devices help protect electric motors and transformers used in commercial and home appliances from damage caused by mechanical overloads, overheating, stall, lost neutral and other potentially harmful conditions. The LVR line-voltage product line of polymeric positive temperature coefficient (PPTC) devices includes components that are rated for line voltages of 120VAC and 240VAC, for up to 2A of operating current at 20°C. They help protect against damage caused by both overcurrent surges and overtemperature faults. They also offer low resistance and are compatibly sized with fuse solutions. Unlike traditional fuses, PolySwitch devices do not require replacement after a fault event. After power has been removed and the overcurrent condition eliminated, the circuit is restored to normal operating condition. Compared to bimetal breakers, they offer greater flexibility, longer lifespan and lower electromagnetic interference (EMI). The PolySwitch LVR devices’ resettable functionality and latching attributes make them a reliable, cost-effective circuit protection solution for both intermittent- and continuous-operation motor applications. Their low resistance, fast timeto-trip, and low profile help circuit designers provide a safe and dependable product, comply with regulatory agency requirements and reduce warranty repair costs. LVR/LVB series are suitable for line-voltage applications up to a continuous operating voltage of 240VAC/120VAC. ## **BENEFITS** - Choice of many devices helps provide engineers with design flexibility - Compatible with high-volume electronics assembly - Assist in meeting regulatory requirements - Higher voltage ratings allow use in new applications ## **FEATURES** - RoHS compliant - Broadest range of radial-leaded resettable devices available in the industry - Current ratings from 50mA to 2A - Line voltage rating of 120VAC and 240VAC - Agency recognition : UL, CSA, TÜV, CQC - Fast time-to-trip - Low resistance ## **APPLICATIONS** - Electromagnetic loads - Game machines - Industrial controls - Lighting ballasts - Loudspeakers - Medical equipment - Motors, fans and blowers - POS equipment - Satellite video receivers - Security and fire alarm systems - Test and measurement equipment - Transformers - USB hubs, ports and peripherals - Intelligent appliance - Robotic machine Specifications subject to change without notice. ©2016 Littelfuse, Inc. 183 RoHS Compliant, ELV Compliant **PolySwitch Resettable Devices** Line-Voltage-Rated Devices ## Table L1 — Product Series - Current Rating, Voltage Rating/Typical Resistance **==> picture [528 x 22] intentionally omitted <==** **----- Start of picture text -----**<br> Voltage Rating LVR 240VAC / 120VAC LVB 240VAC<br>Hold Current (A)<br>**----- End of picture text -----**<br> |**Voltage Rating**<br>**Hold Current(A)**|**LVR 240VAC / 120VAC**|**LVB 240VAC**| |---|---|---| |0.050|25.00Ω|—| |0.080|9.800Ω|—| |0.120|4.800Ω|—| |0.160|3.400Ω|—| |0.250|1.700Ω|—| |0.330|1.000Ω|—| |0.400|0.800Ω|—| |0.550|0.590Ω|—| |0.750|0.400Ω|—| |1.000|0.276Ω|—| |1.250|0.209Ω|0.209Ω| |1.350|—|—| |2.000|0.110Ω|—| ## Table L2 — Thermal Derating [Hold Current (A) at Ambient Temperature (°C)] **==> picture [529 x 247] intentionally omitted <==** **----- Start of picture text -----**<br> Part Maximum Ambient Temperature<br>Number -20°C 0°C 20°C 25°C 40°C 50°C 60°C 70°C 85°C<br>LVR<br>LVR005N 0.08 0.06 0.05 0.05 0.04 0.04 0.03 0.03 0.02<br>LVR008N 0.12 0.10 0.08 0.08 0.07 0.06 0.05 0.04 0.03<br>LVR012 0.18 0.15 0.12 0.12 0.10 0.09 0.07 0.06 0.04<br>LVR016 0.24 0.20 0.16 0.16 0.13 0.11 0.10 0.08 0.05<br>LVR025 0.38 0.32 0.25 0.25 0.21 0.18 0.15 0.13 0.09<br>LVR033 0.50 0.42 0.33 0.33 0.27 0.23 0.20 0.17 0.11<br>LVR040 0.61 0.51 0.40 0.40 0.33 0.28 0.24 0.20 0.14<br>LVR055 0.80 0.68 0.55 0.54 0.46 0.40 0.35 0.29 0.22<br>LVR075 1.23 0.98 0.75 0.74 0.60 0.56 0.49 0.45 0.41<br>LVR100 1.65 1.30 1.00 0.94 0.80 0.75 0.65 0.60 0.55<br>LVR125 2.06 1.63 1.25 1.20 1.00 0.94 0.81 0.75 0.69<br>LVR200 3.30 2.60 2.00 1.97 1.60 1.50 1.30 1.20 1.10<br>LVR075-240 1.23 0.98 0.75 0.74 0.60 0.56 0.49 0.45 0.41<br>LVR100-240 1.65 1.30 1.00 0.94 0.80 0.75 0.65 0.60 0.55<br>LVR125-240 2.06 1.63 1.25 1.20 1.00 0.94 0.81 0.75 0.69<br>LVR200-240 3.30 2.60 2.00 1.97 1.60 1.50 1.30 1.20 1.10<br>Part Maximum Ambient Temperature<br>Number -40°C -20°C 0°C 20°C 25°C 40°C 50°C 60°C 70°C 85ºC<br>LVB<br>LVB125 2.09 1.81 1.53 1.25 1.19 0.99 0.86 0.73 0.60 0.41<br>**----- End of picture text -----**<br> ## Figure L1 — Thermal Derating Curve **A = LVR075-LVR200** **B = LVB125** - **C = LVR005N-LVR055** **==> picture [251 x 166] intentionally omitted <==** **----- Start of picture text -----**<br> 180 A<br>170 B<br>160<br>150<br>140<br>C<br>130<br>120<br>110<br>100<br>90<br>80<br>70<br>60<br>50 A<br>40 C<br>30<br>B<br>20<br>-40 -30 -20 -10 0 10 20 30 40 50 60 70 80 90<br>Ambient Temperature ( )<br>% Rated Hold and Trip Current<br>**----- End of picture text -----**<br> Specifications subject to change without notice. ©2016 Littelfuse, Inc. 184 RoHS Compliant, ELV Compliant **PolySwitch Resettable Devices** Line-Voltage-Rated Devices ## Table L3 — Electrical Characteristics* **==> picture [528 x 38] intentionally omitted <==** **----- Start of picture text -----**<br> VMAX [†] IMAX [†]<br>Lead Size<br>Part IH IT Operating Interrupt Interrupt PD Typ Max.

Operation beyond the maximum ratings or improper use may result in device damage and possible electrical arcing and flame. - A PPTC device is not a fuse - it is a nonlinear thermistor that limits current. Under a fault condition all PPTC devices go into a high-resistance state but do not open circuit, so hazardous voltage may be present at PPTC locations. - The devices are intended for protection against damage caused by occasional overcurrent or overtemperature fault conditions and should not be used when repeated fault conditions or prolonged trip events are anticipated. - In most applications power must be removed and the fault condition cleared in order to reset a PPTC device; however under certain unusual conditions, a PPTC device may automatically reset. PPTC devices should not be used in an application where an automatic reset could create a safety hazard, such as garbage disposals and blenders. Appropriate qualification testing should be performed. - It is the responsibility of the user to determine the need for back-up or failsafe protection to prevent damage that may occur in the event of abnormal function or failure of the PPTC device. - Operation in circuits with a large inductance can generate a circuit voltage (Ldi/dt) above the rated voltage of a PPTC device. This product should not be used in an application where the maximum interrupt voltage or maximum interrupt current can be exceeded by inductive spikes. - Devices are not recommended for reflow soldering. - Device performance can be impacted negatively if devices are handled in a manner inconsistent with recommended electronic, thermal, or mechanical procedures for electronic components. - *PPTC devices are not recommended for installation in applications where the device is constrained such that its PTC properties are inhibited, for example in rigid potting materials or in rigid housings, which lack adequate clearance to accommodate device expansion. - *Contamination of the PPTC material with certain silicone-based oils or some aggressive solvents can adversely impact the performance of the devices. - *Does not apply for LVB devices. ## **Notice:** Information furnished is believed to be accurate and reliable.
