Featuring a capacitance value of 0.1µF and a rated voltage of 400VDC, this component utilizes a robust metallized film construction encapsulated in a flame-retardant epoxy resin coating (UL94V0). The device is engineered for stability across a wide operating temperature range of -55°C to +105°C, exhibiting a capacitance temperature coefficient of -200 ppm/°C to +100 ppm/°C. With low equivalent series resistance (ESR) and high pulse-handling capabilities, it is well-suited for demanding switching power supplies, blocking, and coupling circuits. This radial-leaded capacitor incorporates lead-free tinned copper leads and is characterized by a low self-inductance of less than 1 nH per mm of body and lead length. The 104MPR400K maintains a dissipation factor of 0.1% at 1 kHz and 25°C, ensuring high efficiency in high-frequency filtering and signal conditioning. It is rated for a dv/dt of 300V/µs, providing consistent performance under transient conditions. The component is designed for long-term reliability, evidenced by a load life test of 2,000 hours at +85°C with 125% of rated voltage, resulting in a capacitance change of less than 3%. Its compact physical profile and stable electrical characteristics make it an appropriate solution for industrial and electronic power conversion systems requiring precise, long-term capacitance maintenance. ## Specifications | Parameter | Value | |---|---| | Qualification | - | ## Datasheet 📄 [Download PDF](https://novapart.co/datasheet/farnell:1666087/) FEATURES Small size – Low ESR – Good Pulse Capabilities – Stable with Frequency and Temperature ## APPLICATIONS – – – General Purpose Switching Power Supplies Blocking – Coupling AC Applications (Not across the Line) ~~es~~ **Operating Temperature Range -55°C to +105°C** +10% at 1 kHz, 25°C +5% **Capacitance Tolerance** optional **WVDC 100 250 400 630 1000 Peak, AC voltage (50/60 Hz)** ~~a~~ **VAC** 63 ~~ee~~ 200 220 250 300 ~~a a Se So aoe ome~~ For T>+85°C , The voltage must be decreased by 1.5% per °C **Frequency C<0.1uF 0.1uF5uF (kHz) Dissipation Factor (MAX) 25°C 1** 0.1% 0.1% 0.1% 0.1% 0.1% ~~a COGG———E——EEe~~ **100** 0.4% 0.7% 1.2% 1.8% 2.8% **Insulation Insulation Resistance Capacitance Resistance @25°C (<70% RH)for 1 minute at <0.33μF** 30000 MΩ **100VDC applied** ~~ee eee~~ **>0.33μF** 10000 MΩxμF ~~ee ee~~ **2000 Hours, +85C with 125% of rated voltage** ~~CO ee~~ **Capacitance Change** <3% of initially measured value **Load Life** ~~es~~ **Dissipation Factor** <0.001 at 1kHz and 25°C ~~ee~~ **Insulation Resistance** >50% of maximum specified value **56 days at40°C with 90 to 95%RH, +40°C and no voltage applied Capacitance Change** <3% of initially measured value **Damp Heat test** ~~esa~~ **Dissipation Factor** ~~ee~~ <0.001 at 1kHz and 25°C ~~ee~~ **Insulation Resistance** >50% of maximum specified value ~~rs~~ **Self Inductance** <1 nano-Henry per mm of body length and lead length ~~e~~ **Capacitance Drift Factor** ~~G~~ <0.5% after 2 years at 40°C **Capacitance Temperature** -200 ppm/°C, +100ppm/°C **Coefficient** ~~|~~ **Terminal to Terminal Dielectric Strength** 160% of rated VDC or VAC applied for 2 Seconds and 25°C ~~a~~ **Dielectric** ~~Cn~~ Polypropylene ~~eG~~ **Construction** Metallized film ~~eG~~ **Coating** Flame Retardant epoxy resin (UL94V0) ~~G~~ **Leads** ~~n~~ Lead free tinned copper leads Special Order Options |L MAX|12|18.5|26|31| |---|---|---|---|---| |S+1.0|10|15|22.5|27.5| |G MAX|1.5|1.5|1.5|1.5| |d +0.05|0.6|0.8|0.8|0.8| Email: cdeasia@cde.com Sep-21 **Metallized Polypropylene Epoxy Dipped Radial Lead** ## **MPR** |**WVDC**|**Capacitance**
