UPW1H100MDD

The UPW1H100MDD is a miniature radial-lead aluminum electrolytic capacitor from Nichicon's UPW series, engineered for low impedance and high reliability in power conversion circuits. Its compact φ5 × 11 mm can size, polarized radial-lead package and AEC-Q200 rating make it suitable for space-constrained power-supply designs and demanding environments where stable filtering and ripple handling are required.

Key value comes from a 10 µF capacitance at 50 V, a wide operating temperature range (−55 °C to +105 °C) and rated endurance under elevated temperature, delivering consistent performance in switching power supplies and similarly demanding applications.

Key Features

• Capacitance & tolerance — 10 µF nominal with tolerance −20% to +20% (±20%).
• Rated voltage — 50 V DC for common power-rail and DC-link applications.
• Low impedance / ripple handling — Specified ripple current: 36 mA at 120 Hz (low frequency) and 120 mA at 10 kHz (high frequency), supporting effective smoothing and decoupling in switching supplies.
• Leakage current — Rated leakage current: 15 µA, useful for low-leakage power designs.
• Temperature and endurance — Operating range −55 °C to +105 °C with qualified life of 2000 hours at 105 °C.
• Package & mounting — Radial-lead, can-style package (φ5 × 11 mm) with 2.0 mm lead spacing (±0.5 mm), suitable for through-hole mounting and robust mechanical retention.
• Polarized — Designed as a polarized aluminum electrolytic capacitor for DC applications.
• AEC-Q200 rated — Built to AEC-Q200 criteria for enhanced reliability in demanding applications.
• Packaging options — Supplied in bulk (no terminal forming) or bag packing to match assembly and prototyping needs.
• Product status — End Of Life.

Typical Applications

• Switching power supplies — Low impedance and specified ripple current make this capacitor suitable for output filtering and smoothing in SMPS circuits.
• Automotive electronic modules — AEC-Q200 rating and wide temperature range support use in automotive electronics for decoupling and local energy storage.
• Embedded and industrial equipment — Compact radial package and robust endurance suit power-filtering and decoupling in space-constrained controllers and industrial power subsystems.

Unique Advantages

• Compact footprint for dense layouts: φ5 × 11 mm can size minimizes board area while providing useful capacitance at 50 V rails.
• Designed for ripple performance: Separate ripple-current specifications at 120 Hz and 10 kHz allow designers to assess low- and high-frequency ripple handling directly.
• Wide temperature capability: −55 °C to +105 °C operation supports deployments across harsh thermal environments.
• AEC-Q200 reliability: Qualification to AEC-Q200 provides an added level of component reliability for demanding applications.
• Low leakage for sensitive circuits: 15 µA leakage current helps preserve performance in low-current and standby conditions.
• Through-hole robustness: Radial-lead mounting offers mechanical strength for applications subjected to vibration or handling.

Why Choose UPW1H100MDD?

UPW1H100MDD combines the UPW series' miniature, low-impedance design with a 50 V rating and a compact radial-lead package — a practical choice for engineers needing reliable filtering and decoupling in constrained board space. The capacitor's wide operating temperature range, defined ripple-current specs, and AEC-Q200 rating make it suitable for designs that demand predictable behavior under thermal and electrical stress.

This part is best suited for applications where a small can-style aluminum electrolytic with established endurance and low leakage is required. Its packaging options and through-hole form factor simplify assembly choices for prototyping and production alike.
