Key Features

• Capacitance & Voltage — 1.2 mF capacitance at a 250 V rated voltage with ±20% tolerance.
• High Ripple Current & Frequency Behavior — Rated ripple current specified at 3.45 A (120 Hz) and 5.175 A (50 kHz); frequency coefficients for the 200–250 V range include 0.81 at 50 Hz, 1.00 at 120 Hz and up to 1.50 at 50 kHz or more.
• Thermal Endurance — Designed for continuous operation to 105 °C and certified to withstand 3000 hours of rated ripple current at 105 °C with defined endurance limits for capacitance, tan δ and leakage current.
• Reliability Specifications — Endurance: capacitance change within ±20% after test; tan δ ≤ 200% of initial; leakage current ≤ initial specified value. Shelf life: 1000 hours at 105 °C with post-conditioning limits defined in the datasheet.
• Package & Mounting — Radial can, snap‑in terminal type for robust mechanical retention on the PCB.
• Leakage Current Limit — Leakage current specified by I ≤ 3√CV (µA) after 5 minutes at 20 °C (C = µF, V = V), per the product datasheet.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
• Physical Size — Nominal footprint dimensions: L: 5 × D: 3 cm (radial can form factor).

Typical Applications

• General‑Purpose Power Systems — For general-purpose circuits that require 1.2 mF at 250 V with high ripple endurance at elevated temperatures.
• High‑Ripple Current Circuits — Suitable where rated ripple current and frequency-dependent ripple handling (values provided at 120 Hz and 50 kHz) are required.
• Industrial Electronics — Use in industrial equipment designs that demand operation across –40 °C to +105 °C and long ripple-current endurance.

Unique Advantages

• Long-Term Ripple Endurance: Specified to withstand 3000 hours of rated ripple current at 105 °C, providing predictable life performance under sustained ripple stress.
• High-Frequency Ripple Capability: Ripple current specifications at both low and high frequencies (3.45 A at 120 Hz, 5.175 A at 50 kHz) plus frequency coefficients allow designers to size capacitors confidently across switching frequencies.
• Wide Operating Temperature: Rated for –40 °C to +105 °C operation, enabling use in elevated-temperature environments within the specified range.
• Robust Mounting: Snap‑in radial can package offers secure PCB retention for assemblies requiring mechanical stability.
• Measured Reliability Metrics: Endurance and shelf‑life limits for capacitance, dissipation factor (tan δ) and leakage current are defined in the datasheet for clear qualification criteria.
• Regulatory Compliance: RoHS compliance supports regulatory requirements for restricted substances.
