URS2E101MHD

The URS2E101MHD from Nichicon is a miniature, low‑profile aluminum electrolytic capacitor in the URS series, configured as a radial‑lead can for through‑hole mounting. It delivers 100 µF of capacitance at a rated voltage of 250 V and is specified for general purpose applications where a compact, polarized electrolytic capacitor is required.

Designed for sustained operation across a wide ambient range (–40 °C to +85 °C) and specified for 2,000 hours at 85 °C, this component balances compact form factor with durability and defined ripple current performance for power‑related smoothing and filtering tasks.

Key Features

• Electrical Performance — 100 µF capacitance with a rated voltage of 250 V and polarization suitable for DC smoothing and energy‑storage roles in general‑purpose circuits.
• Compact Radial Can Package — Radial lead, can‑style package with 7.5 mm lead spacing and physical dimensions L: 25 mm × D: 18 mm, optimized for space‑constrained through‑hole layouts.
• Operating Temperature & Endurance — Operates from –40 °C to +85 °C and meets endurance life of 2,000 hours at 85 °C with specified limits on capacitance change, tangent of loss angle, and leakage current after the test.
• Leakage Current Specification — Leakage current behavior follows the series specification: after 1 minute ≤ 0.03CV (µA) and after 2 minutes ≤ 0.01CV (µA), providing predictable DC leakage characteristics.
• Ripple Current Capability — Rated ripple current of 590 mA at 120 Hz and 944 mA at 10 kHz, enabling defined AC ripple handling across low and high frequency conditions.
• Capacitance Tolerance — ±20% tolerance at 120 Hz, 20 °C, matching common design margins for electrolytic components.

Typical Applications

• General Purpose Electronics — Suitable for general purpose circuits that require a polarized aluminum electrolytic capacitor with 100 µF at 250 V.
• Power Supply Smoothing — Used where defined ripple current handling and DC filtering are required within the specified temperature and lifetime constraints.
• Through‑Hole PCB Designs — Radial lead can format and 7.5 mm lead spacing make this part appropriate for traditional through‑hole assembly and repairable designs.

Unique Advantages

• Compact, Low‑Profile Form — Small can dimensions (L: 25 mm × D: 18 mm) help reduce board real estate while retaining required capacitance and voltage rating.
• Defined Thermal Endurance — Rated for 2,000 hours at 85 °C, providing designers with a clear reliability specification for lifetime planning.
• Predictable Leakage Behavior — Series leakage current formula and measured limits enable accurate power‑budgeting and startup behavior analysis.
• Frequency‑aware Ripple Ratings — Supplied ripple current values for both 120 Hz and 10 kHz give concrete data for AC ripple and decoupling design decisions.
• Standardized Tolerance — ±20% tolerance simplifies selection for common electrolytic capacitor use cases and BOM standardization.
