Key design attributes include a compact φ20 × 35 mm can, tray packing for production handling, and performance specified to 105°C with a rated endurance of 3000 hours under rated ripple current conditions.

Key Features

• Capacitance & Voltage — 390 μF nominal capacitance with a 180 V rated voltage and tolerance of −20% to +20%.
• Snap‑In Radial Package — φ20 × 35 mm radial, can‑type snap‑in mounting for secure PCB installation and mechanical stability.
• High Temperature Endurance — Endurance specified for 3000 hours at 105°C when subjected to rated ripple current, per series specification.
• Ripple Current Capability — Low‑frequency ripple current 1.3 A (120 Hz) and high‑frequency ripple current 1.95 A (50 kHz) to support a range of operating frequencies.
• Low Dielectric Loss — Tan δ (loss tangent) of 0.15 measured at 20°C, 120 Hz, providing predictable dissipation characteristics.
• Leakage Current — Specified leakage current of 790 μA (measured after rated voltage application conditions as defined in the product data).
• Wide Operating Temperature — Rated for operation from −40°C to +105°C.
• Environmental Compliance — RoHS‑compliant materials and manufacturing.
• Production Ready — Part is in mass production and supplied in tray packing for assembly workflows.

Typical Applications

• General‑purpose power systems — Provides 390 μF at 180 V in a snap‑in form factor for general‑purpose electronic and power circuitry.
• High‑temperature environments — Specified endurance of 3000 hours at 105°C for applications demanding sustained elevated temperature performance.
• Production assembly — Tray packing and snap‑in terminals support automated handling and repeatable placement in volume manufacturing of general‑purpose equipment.

Unique Advantages

• Long endurance at rated conditions — 3000 hours at 105°C under rated ripple current helps extend service life in demanding thermal environments.
• Measured ripple performance — Defined low‑ and high‑frequency ripple currents (1.3 A at 120 Hz and 1.95 A at 50 kHz) let designers size capacitors against actual ripple loads.
• Predictable loss characteristics — Tan δ of 0.15 (20°C, 120 Hz) provides a quantified dielectric loss metric for thermal and stability calculations.
• Compact snap‑in package — φ20 × 35 mm can with snap‑in terminals delivers a space‑efficient solution for radial mounting while providing mechanical retention.
• Production‑friendly supply — Mass production status and tray packing simplify procurement and assembly planning.
• Regulatory compliance — RoHS compliance supports environmental and regulatory requirements for electronic assemblies.
