## **POLYSWITCH RESETTABLE DEVICES** Surface-Mount Devices 

PolySwitch surface-mount devices are an effective circuit protection method for computer, consumer, multimedia, portable and automotive electronics applications. 

In an affort to reduce the size and cost of surfacemount devices, Littelfuse PolySwitch team introduced the miniSMD product series in 1995. Subsequently, we developed the microSMD, nanoSMD, picoSMD and femtoSMD family of products. The femtoSMD series reduced the device size to a 1608mm (0603 mils) footprint, which is one-twelfth the size of the popular miniSMD series. 

Recent additions to the PolySwitch surface-mount series include 1.1A picoSMD 1210mm (0805 mils) and 0.35A femtoSMD 1608mm (0603 mils) devices. 

## **BENEFITS** 

- Smaller size helps save board space and cost 

- Many product choices optimizes design flexibility 

- Compatible with high-volume electronics assembly 

- Assists in meeting regulatory requirements 

- Higher voltage ratings allow use in new applications 

## **APPLICATIONS** 

- Computer 

- Portable electronics 

- Multimedia 

- Game machines 

- Telephony and broadband 

- Mobile phones 

## **FEATURES** 

- RoHS compliant 

- Halogen free 

   - Automotive 

   - Industrial controls 

   - Battery 

- (refers to: Br _[≥]_ 900ppm, Cl _[≥]_ 900ppm, Br+Cl _[≥]_ 1500ppm) 

- Broadest range of resettable devices available in the industry 

- Current ratings from 0.05 to 3.1A 

- Voltage ratings from 6V computer and electronic applications to 60V telecom applications 

- Agency recognition: UL, CSA, TÜV 

- Small footprint 

- Fast time-to-trip 

- Low resistance

## Solder Reflow 

- Recommended reflow methods: 

   - IR 

   - Hot air 

   - Nitrogen 

- Recommended maximum paste thickness: 0.25mm (0.010in) 

- Devices can be cleaned using standard methods and aqueous solvents. 

- Experience has shown the optimum conditions for forming acceptable solder fillets occur when a reasonable amount of solder paste is placed underneath each device’s termination.  As such, we request that customers comply with our recommended solder pad layouts. 

- Customer should validate that the solder paste amount and reflow recommendations meet its application. 

- We request that customer board layouts refrain from placing raised features (e.g. vias, nomenclature, traces, etc.) underneath PolySwitch devices. It is possible that raised features could negatively impact solderability performance of our devices. 

## Rework 

- femtoSMD, picoSMD, nanoSMD, microSMD, miniSMD and SMDC series: standard industry practices. (Please also avoid direct contact to the device.) 

- SMD series: Rework should be confined to removal of the installed product and replacement with a fresh device.

## **Warning :** 

- Users should independently evaluate the suitability of and test each product selected for their own application. 

- Operation beyond the maximum ratings or improper use may result in device damage and possible electrical arcing and flame. 

- These 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. 

- Contamination of the PPTC material with certain silicone-based oils or some aggressive solvents can adversely impact the performance of the devices. 

- Device performance can be impacted negatively if devices are handled in a manner inconsistent with recommended electronic, thermal, and 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. 

- Operation in circuits with a large inductance can generate a circuit voltage (Ldi/dt) above the rated voltage of the device.
