Product Overview
This Southern Electronics Company (SEC) MPP5X is a precision metallized polypropylene film capacitor engineered for stable dielectric performance in DC circuits. Rated at 0.56 microfarads and 50 volts DC, this rectangular radial component delivers low dielectric absorption and stable capacitance across varying operational frequencies. Sourced originally from industrial communications inventory, it serves maintenance technicians restoring legacy GE and Ericsson radio hardware as well as analog audio builders seeking reliable vintage polypropylene characteristics.
Key Features
- Dielectric: Metallized polypropylene (MPP)
- Capacitance: 0.56 uF (.56 MFD / 560 nF)
- Voltage rating: 50 VDC
- Capacitance tolerance: +-10%
- Package style: Rectangular epoxy-encapsulated radial box
- Lead spacing: 15 mm pitch with extended through-hole wire leads
- Date code marking: 84.07 (Manufactured week 7, 1984)
Applications
- Replacing degraded filter and bypass capacitors in vintage two-way radio base stations and communications chassis.
- Analog audio tone-shaping, crossover networks, and guitar effects pedals requiring polypropylene dielectric properties.
- Bench breadboarding, timing pulse networks, and hobbyist synthesizer circuits where low dielectric loss is critical.
Frequently Asked Questions
What are the physical dimensions of the capacitor body?
The encapsulated rectangular body measures approximately 18 mm long by 10 mm high by 5 mm thick, with a 15 mm lead pitch.
Is this capacitor polarized?
No. Metallized polypropylene film capacitors are non-polar components and can be oriented in either direction within a circuit.
Why choose an individually listed vintage capacitor rather than a bulk surplus lot?
Purchasing an individual piece avoids buying full reels or uninspected grab bags when servicing a single circuit board. Each component is visually checked for lead condition and clear markings before shipment. Shipping is $8 flat rate, free once the order passes $28, and orders leave the Idaho warehouse the same or next business day.
Forty years in storage and the leads are still straight and untrimmed. A genuine American-made polypropylene film block ready to drop straight into a classic circuit build.
