• Wide operating temperature — Usable from −55°C to 105°C to cover a broad range of environmental conditions.
• Low loss (tan δ) — tanδ = 0.12 measured at 20°C, 120 Hz, supporting efficient AC performance at line frequencies.
• Ripple current capability — Low-frequency ripple current 68 mA at 120 Hz and high-frequency ripple current 136 mA at 10 kHz for effective smoothing across a range of ripple spectra.
• Low leakage current — Specified leakage current of 33 µA after 1 minute at 20°C, minimizing standby losses in DC circuits.
• Compact radial-can package — Small footprint (φ5 × 11 mm) with radial leads and 2 mm lead spacing (±0.5 mm) for dense PCB layouts and straightforward through-hole mounting.
• RoHS compliant — Conforms to RoHS environmental requirements.
• Packaging options — Supplied in bulk (no terminal forming) or bag packing to suit assembly and prototyping workflows.

Typical Applications

• Power supply filtering — Provides local bulk capacitance and smoothing for low-to-moderate voltage power rails up to 50 V.
• Decoupling for compact electronics — Compact φ5 × 11 mm can suits space-constrained control boards and modules requiring through-hole components.
• General-purpose energy storage — Useful for transient energy buffering and charge-holding in a variety of consumer and industrial electronics where 22 µF at 50 V is appropriate.

Unique Advantages

• Small form factor: φ5 × 11 mm radial can enables high-density PCB layouts while retaining through-hole robustness.
• Temperature resilience: −55°C to 105°C rating supports reliable operation across wide ambient and internal temperature ranges.
• Defined high-temperature life: 1000-hour endurance at 105°C provides predictable aging behavior for thermal stress planning.
• Frequency-aware ripple performance: Specified ripple current values at 120 Hz and 10 kHz let designers assess smoothing performance across both low and high-frequency noise.
• Low leakage: 33 µA leakage current reduces idle power draw in DC applications.
• Regulated tolerance and loss: ±20% capacitance tolerance and tanδ = 0.12 (20°C, 120 Hz) facilitate reliable circuit behavior and impedance planning.
