Type LP 105 oC Snap-In Aluminum Electrolytic Capacitors
Stable ESR, Long Life, Snap-In
Specifications
Capacitance Range:
Voltage Range:
Capacitance tolerance:
Operating Temperature Range:
Dissipation Factor:
Type LP radial snap-in aluminum electrolytic
capacitors are small in size and are rated for low
voltage applications. Their durable construction
guarantees a long life while operating up to 105 oC
with a stable ESR. These features make the Type LP
ideal for use in switch-mode power supplies.
