UPS1H100MDD

The UPS1H100MDD is a miniature, low-impedance aluminum electrolytic capacitor from Nichicon’s UPS series, designed for use in switching power supplies and general-purpose power-filtering applications. Its compact radial-can package, polarized design and wide operating temperature range make it suitable for space-constrained power-rail decoupling and ripple smoothing tasks.

Key value comes from a combination of compact dimensions, rated performance at 50 V, and robustness across –55 °C to +105 °C, supporting reliable operation in demanding thermal environments.

Key Features

• Capacitance & Voltage — 10 µF rated capacitance at a 50 V rated voltage for power-decoupling and smoothing duties.
• Compact Radial Can Package — Radial lead, can-style package with lead spacing of 2 mm and overall dimensions of L: 1.1 × D: 0.5 cm for tight board layouts.
• Polarized Construction — Polar capacitor suitable for typical DC power applications.
• Tolerance & Loss — Capacitance tolerance ±20% and tangent of loss angle (tan δ) max. 0.10 (measured at 120 Hz, 20 °C for 50 V devices), enabling predictable AC performance.
• Ripple Performance — Rated ripple current: 20.4 mA at 120 Hz and 120 mA at 10 kHz, supporting AC ripple handling in switching regulator outputs.
• Leakage Current — Leakage current specification: after 1 minute’s application of rated voltage at 20 °C, ≤ 0.03 C·V (µA), where C is capacitance (µF) and V is rated voltage (V).
• Wide Temperature & Life — Operating temperature range –55 °C to +105 °C with a specified lifetime of 2000 hours at 105 °C.
• RoHS Compliant — Conforms to RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Switching Power Supplies — Local output filtering and ripple suppression where a compact, polarized electrolytic is required.
• DC-DC Converters — Input/output decoupling and energy storage in space-constrained converter designs.
• Industrial Control Electronics — Power-rail smoothing in industrial instrumentation and control modules operating across a wide temperature range.
• Consumer Power Modules — Compact power-filtering in consumer devices that need reliable decoupling on limited board area.

Unique Advantages

• Space-saving form factor — Small can dimensions (L: 1.1 × D: 0.5 cm) and 2 mm lead spacing make board layout easier in dense assemblies.
• Measured AC performance — Specified ripple current values at 120 Hz and 10 kHz allow designers to evaluate ripple handling for both low- and high-frequency components.
• Predictable leakage behavior — Leakage current limited to ≤ 0.03 C·V (µA) after 1 minute at 20 °C provides quantifiable standby and bias current expectations.
• Durable across temperature — Rated for –55 °C to +105 °C and 2000 h life at 105 °C, supporting applications with extended thermal exposure.
• Regulatory compliance — RoHS conformity simplifies selection for regions and customers requiring restricted-substance compliance.

Why Choose UPS1H100MDD?

UPS1H100MDD combines a compact radial-can package with clear, measured performance characteristics—10 µF at 50 V, defined ripple current at multiple frequencies, and a quantifiable leakage-current formula—making it straightforward to evaluate and integrate into power-supply and decoupling designs. Its wide operating temperature range and specified lifetime at elevated temperature provide predictable reliability for applications exposed to thermal stress.

This part is well suited to engineers specifying small-footprint electrolytic capacitors for switching regulators, DC-DC converters, and general power-filtering tasks where verifiable electrical and environmental specifications are required.
