Description

Sourced and supplied by Al Imran Enterprises, Lahore, Pakistan. The RIFA PHE448 is a radial-leaded polypropylene film/foil pulse capacitor engineered for high-voltage, high-frequency duty in demanding industrial electronics. RIFA, the capacitor specialist whose technology now lives on within KEMET, built the F448 family around a full polypropylene film dielectric with foil electrodes, delivering very low dissipation factor, exceptionally high insulation resistance and stable behaviour under repetitive fast-rise-time pulses. Across the series, rated voltages span 1600 V DC to 2000 V DC (650 V AC to 700 V AC) with capacitance values up to 22 nF graded to a tight ±5% tolerance on the E12 series, making the family a dependable choice for snubber networks, switching-power stages, induction-heating circuits and pulse-forming applications. The radial lead configuration uses a standard 15 mm ±0.4 mm pitch with 0.8 mm diameter tinned leads, dropping straight into conventional PCB layouts without re-drilling. The self-extinguishing UL94 V-0 encapsulation is qualified to climatic category 55/105/56, so the capacitor withstands 56 days of damp heat and keeps its electrical characteristics across a -55 °C to +105 °C temperature range, derating gracefully above +85 °C. Insulation resistance is specified at no less than 100,000 MΩ and dissipation factor at 1 kHz stays at or below 0.03%, figures that matter when capacitors sit continuously across fast-switching semiconductors. Every unit leaves the factory in Finland marked with the capacitance code per IEC 60062 together with the RIFA brand mark, so incoming inspection can verify authenticity at a glance. At Al Imran Enterprises we keep genuine RIFA and KEMET pulse capacitors moving to maintenance teams across Pakistan's process industries. Sugar mills, cement plants, textile mills and steel re-rolling plants rely on drive systems, soft starters, UPS cabinets and medium-frequency equipment where original pulse capacitors are often the first components stressed, and where sourcing a genuine replacement quickly prevents hours of downtime. Our team verifies part markings, ratings and date codes before dispatch, and supports engineering departments with cross-referencing against legacy RIFA type codes.

PHE 448 1250 — Frequently Asked Questions

What is the RIFA PHE448 capacitor used for?▾
The PHE448 is a polypropylene film/foil pulse capacitor designed for high-voltage, high-frequency duty such as snubber networks across IGBTs, drive stages and induction-heating circuits.
What is the capacitance value of this specific unit?▾
The unit we hold follows the PHE448 series construction; the exact capacitance code on the body should be confirmed from the marking before design-in. The series spans 0.1 nF to 22 nF at ±5% tolerance.
What voltage does the PHE448 series handle?▾
The series is rated 1600 V DC to 2000 V DC (650 V AC to 700 V AC), which is why it suits snubber and pulse applications where ordinary capacitors degrade quickly.
Is the PHE448 still manufactured?▾
RIFA's capacitor technology continues under KEMET following the brand acquisition, and the F448/PHE448 construction remains the reference for pulse film duty. We source current and recent-date stock.
Where can I buy RIFA PHE448 capacitors in Pakistan?▾
Al Imran Enterprises, based at Rehman Street No. 4, Nishtar Road, Lahore, is a trusted supplier of genuine RIFA and KEMET capacitors in Pakistan. Contact us for pricing and delivery.
