UPS1A101MDD

The UPS1A101MDD is a miniature, radial-lead aluminum electrolytic capacitor designed for low-impedance, low-voltage applications. It delivers 100 µF capacitance at a 10 V rating with a compact φ5×11 mm can and 2 mm lead spacing for space-constrained through-hole designs.

Engineered for general-purpose and switching power supply use, this RoHS-compliant part provides low leakage and defined ripple-current capability across low- and high-frequency conditions, with an operating temperature range of −55 °C to 105 °C and a rated life of 2000 hours at 105 °C.

Key Features

• Capacitance & Voltage — 100 µF nominal capacitance with ±20% tolerance, rated for 10 V operation.
• Low-loss performance — Tangent of loss angle (tanδ) 0.20 (measured at 20 °C, 120 Hz) to support stable filtering at the rated voltage and frequency.
• Ripple current handling — Low-frequency ripple current 80 mA (120 Hz) and high-frequency ripple current 160 mA (10 kHz), suitable for decoupling and smoothing in switching supplies.
• Low leakage — Leakage current specified at 30 µA, aiding in low-standby-loss designs and predictable bias behavior.
• Robust temperature range — Rated for −55 °C to 105 °C to accommodate a wide array of environmental conditions.
• Compact radial package — φ5×11 mm aluminum can, radial lead mounting, 2 mm lead spacing (±0.5 mm), packaged in bulk or bag format for through-hole assembly.
• Regulatory — RoHS-compliant construction.

Typical Applications

• Switching Power Supplies — Local decoupling and smoothing where compact, low-impedance capacitors are required for stable regulation.
• Low-Voltage Power Filtering — Bulk and decoupling capacitance for 10 V-class rails in consumer and industrial electronics.
• Space-Constrained Through-Hole Designs — Small φ5×11 mm can and short radial leads make it suitable for compact PCB layouts requiring through-hole components.

Unique Advantages

• Small footprint, through-hole convenience — φ5×11 mm size with 2 mm lead spacing enables high-density PCB placement while retaining through-hole mounting robustness.
• Predictable ripple performance — Specified ripple currents at both low and high frequencies allow designers to size capacitors confidently for switching applications.
• Low steady-state leakage — 30 µA leakage current supports low-bias-loss circuits and predictable capacitor behavior after power application.
• Wide operating range — −55 °C to 105 °C rating supports a variety of environmental conditions without broad derating of selection.
• RoHS compliance — Meets RoHS directive requirements for restricted substances in electronic assemblies.
• Packaging flexibility — Available in bulk (no terminal forming) or bag packing to suit assembly flow and inventory handling.
