• Temperature Range — Specified operating range from −40 °C to 85 °C to cover common ambient and equipment conditions.
• Endurance at Elevated Temperature — Designed to withstand 3000 hours of D.C. bias plus rated ripple current at 85 °C with defined limits on capacitance change, tan δ, and leakage current.
• Ripple Current Performance — Rated ripple current of 1.68 A at 120 Hz and 2.52 A at 50 kHz to support AC ripple handling across low and higher frequencies.
• Polarized Device — Polarized capacitor type; observe polarity in circuit implementation.
• RoHS Compliant — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).
• Size — Compact radial can dimensions listed as L: 3.5 × D: 2 cm for space‑conscious layouts.

Typical Applications

• General Purpose Electronics — For general‑purpose circuits requiring polarized bulk capacitance at 250 V.
• Systems Operating to 85 °C — Components and equipment that require capacitors qualified for operation up to 85 °C and defined ripple endurance.
• PCB Assemblies with Snap‑In Mounting — Suited for designs that accept radial can, snap‑in terminals for robust mechanical attachment.

Unique Advantages

• High Stored Energy at 250 V: 330 µF capacitance paired with 250 V rating provides substantial charge storage for smoothing and bulk energy needs within the specified voltage.
• Proven Endurance: Rated to withstand 3000 hours of rated ripple‑current application at 85 °C, with defined post‑endurance limits on capacitance, tan δ and leakage current.
• Broad Operating Temperature: −40 °C to 85 °C operating range supports a wide span of ambient conditions encountered in general‑purpose equipment.
• Dual‑Frequency Ripple Ratings: Specified ripple current at both 120 Hz (1.68 A) and 50 kHz (2.52 A) to support designs encountering different ripple frequency profiles.
• Secure Snap‑In Mounting: Snap‑in radial can package enables reliable board retention for through‑hole assemblies.
• Regulatory Compliance: RoHS compliance aligns with environmental requirements for many commercial and industrial products.
