UEP1C100MDD

The UEP1C100MDD is a Nichicon UEP series aluminum electrolytic capacitor designed for bi‑polarized operation over a wide temperature range. It delivers 10 µF capacitance at a 16 V rating in a compact radial can (φ5 × 11 mm) with 2 mm lead spacing, intended for general‑purpose electronic designs that require a small, reliable electrolytic capacitor.

Key value comes from its bi‑polarized construction, wide operating temperature range (−55 °C to 105 °C) and defined endurance (1000 hours at 105 °C), providing predictable behavior in demanding ambient conditions and reversible polarity applications.

Key Features

• Bi‑Polarized Construction  Designed for bi‑polar operation and validated in the UEP series for polarity inversion endurance.
• Electrical Characteristics  10 µF rated capacitance with ±20% tolerance and a 16 V rated voltage; tan δ specified at 0.20 (120 Hz, 20 °C) and leakage current specified (4.8 µA for this part).
• Wide Temperature Range  Operational from −55 °C to 105 °C, enabling use across a broad set of ambient conditions.
• Endurance & Reliability  Rated for 1000 hours at 105 °C with polarity inversion every 250 hours as part of endurance verification.
• Package & Mounting  Compact radial can package (φ5 × 11 mm, L: 1.1 × D: 0.5 cm) with 2 mm lead spacing for through‑hole, radial lead mounting; available in bulk or bag packing (no terminal forming).
• Ripple Performance  Ripple current ratings include 30 mA at 120 Hz and 60 mA at 10 kHz, with frequency coefficients defined for higher‑frequency operation.
• RoHS Compliant  Meets RoHS requirements for applications requiring restricted‑substance compliance.

Typical Applications

• General‑purpose electronic circuits  Suitable where a small, bi‑polarized aluminum electrolytic capacitor is needed for general circuit filtering and decoupling.
• Polarity‑reversible circuits  Fits designs that require capacitors capable of withstanding polarity inversion and wide temperature swings.
• Temperature‑sensitive environments  Useful in equipment expected to operate across −55 °C to 105 °C given the specified operating range and endurance.

Unique Advantages

• Bi‑polarized capability: Supports applications requiring reversible polarity operation as defined by the UEP series testing.
• Wide operating temperature: −55 °C to 105 °C rating provides design margin for harsh ambient conditions.
• Documented endurance: 1000 hours at 105 °C (with polarity inversion test protocol) offers predictable long‑term behavior for thermal stress scenarios.
• Compact radial package: φ5 × 11 mm can with 2 mm lead spacing conserves board space while allowing through‑hole mounting.
• Low standby leakage: Specified leakage current (4.8 µA) helps minimize quiescent current in sensitive designs.
• Defined ripple handling: Ripple current specifications at 120 Hz and 10 kHz support both low‑ and high‑frequency ripple filtering needs.

Why Choose UEP1C100MDD?
