Film capacitor: miniaturized MKP series

Photocoupler

The EPCOS MKP B3267*P* series of film capacitors from the TDK Group has a very small volume, for example a capacitance of 1 μF and a voltage rating of 450 V DC. The capacitance is extremely high and the lead spacing is only 10 mm, only 8.0 x 17.5 x 13.0 mm3. Compared to previous capacitive models with lead spacing of 15 mm, the volume is reduced by approximately 40%.

The lead spacing for the new product line is 10 mm, 15 mm and 22.5 mm. They are rated at 450 V DC, 520 V DC and 630 V DC, with capacitance values ranging from 68 nF to 2.2 μF, suitable for continuous operation at 125 °C. The plastic housing of this product range meets UL 94 V-0 specifications and is available in halogen-free versions upon request.

Typical applications for this family of capacitors are ballasts, rectified output filter capacitors for LED power supplies and switching power supplies, or passive PFC capacitors.

the term

• UL 94 V-0: Flame retardancy rating of plastics. No burning material is allowed to fall on the V-0 level, and any flame must be automatically extinguished within 10 seconds.
• Halogen: Chemical elements added to plastics such as bromine, iodine, and chlorine.

main application

• Passive PFC circuit
• Power output filtering

Main features and benefits

• The package size is reduced: for example, the capacitance value of 1 μF and the rated voltage of 450 V DC are only 8.0 x 17.5 x 13.0 mm3 and the lead pitch is only 10 mm.
