UUN1H101MNJ1MS

The UUN1H101MNJ1MS from Nichicon is a chip‑type, bi‑polarized aluminum electrolytic capacitor in the UUN series, rated 100 µF at 50 V. It is designed for surface mounting on high‑density PCBs and is compatible with automatic mounting machines fed with carrier tape.

Engineered for wide operating environments, this RoHS‑compliant capacitor supports operation from −55 °C to +105 °C and offers an endurance specification of 2000 hours at 105 °C (with polarity inversion every 250 hours), making it suitable for general‑purpose electronic designs that require higher capacitance in an SMD package.

Key Features

• Capacitance & Voltage — 100 µF capacitance rated at 50 V for general‑purpose energy storage and filtering.
• Bi‑Polarized Construction — Bi‑polarized design enables AC‑coupling and bipolar signal operation without polarity constraints typical of polarized electrolytics.
• Wide Temperature Range — Specified to operate from −55 °C to +105 °C for demanding environmental conditions.
• Endurance — Lifetime rating of 2000 hours at 105 °C with periodic polarity inversion as defined in the series endurance test conditions.
• Leakage Current — Leakage current ≤ 0.03CV (µA) after 1 minute at 20 °C when rated voltage is applied, per series specification.
• Loss Tangent (tan δ) — Series characteristic at 50 V: tan δ (max.) 0.12 measured at 120 Hz and 20 °C.
• Ripple Current — Specified ripple current of 230 mA at 120 Hz and 345 mA at 10 kHz; frequency coefficients apply per datasheet for high‑frequency operation.
• Surface‑Mount Chip Package — Chip type (radial, can SMD) designed for placement on high‑density PCBs; recommended land pattern size 1.28 × 1.28 cm.
• Tolerance & Marking — Capacitance tolerance ±20%; case top marked with black print for easy identification. RoHS‑compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General‑purpose power filtering — Bulk decoupling and smoothing on high‑density PCBs where an SMD package and higher capacitance are required.
• AC coupling and signal paths — Bi‑polarized construction supports bipolar signal applications and AC‑coupling without polarity restrictions.
• Industrial and communications equipment — Suited for devices that require wide operating temperature range and long endurance at elevated temperatures.

Unique Advantages

• Bi‑polarized flexibility: Enables use in AC or bipolar signal circuits without polarity limitations, simplifying circuit design where polarity may vary.
• High capacitance in an SMD package: Offers 100 µF in a chip‑type can SMD form factor for space‑constrained, high‑density PCB layouts.
• Wide operating temperature: −55 °C to +105 °C rating supports a broad range of environmental conditions and thermal stress.
• Endurance and reliability: 2000‑hour endurance at 105 °C (with polarity inversion schedule) provides predictable lifetime behavior in elevated‑temperature applications.
• Measured ripple performance: Published ripple current values at 120 Hz and 10 kHz help engineers size capacitors for both low‑ and high‑frequency filtering tasks.
• Automated assembly ready: Designed for carrier‑tape feeding and automatic placement to support high‑volume manufacturing processes.
