UCH1E151MCL1GS

The UCH1E151MCL1GS is a chip‑type, high‑reliability aluminum electrolytic capacitor in a compact surface‑mount can. It delivers 150 µF at 25 V with polarized construction, designed for demanding environments that require stable capacitance, controlled ESR, and long life.

Engineered for automotive and other harsh‑environment electronics, this part offers AEC‑Q200 qualification, a wide operating temperature range from −40 °C to 125 °C, and a proven endurance rating of 2000 hours at 125 °C.

Key Features

• Capacitance & Voltage: 150 µF rated capacitance at 25 V with ±20% tolerance, suitable for bulk decoupling and power filtering needs.
• Temperature Range & Reliability: Rated for −40 °C to 125 °C and AEC‑Q200 qualified, providing specification-backed performance across automotive temperature extremes.
• Low‑temperature ESR Specification: Low temperature ESR and an added ESR specification after the −40 °C test improve performance predictability in cold environments.
• Endurance: Rated endurance of 2000 hours at 125 °C; capacitance, tan δ and leakage current limits are defined after the endurance test.
• Ripple Handling: Specified ripple currents of 98.5 mA at 120 Hz and 197 mA at 10 kHz, with frequency coefficients provided for higher frequencies.
• Surface‑Mount Package: Chip type radial can SMD package sized L: 7.7 × D: 6.3 mm with recommended land size L: 6.6 × W: 6.6 mm; compatible with automatic mounting via carrier tape.
• Electrical Characteristics: ESR specified at 300 mΩ (100 kHz) and leakage current limited to 0.01CV (μA) after 2 minutes at 20 °C.
• Compliance: RoHS‑compliant and marked with black print on the case top for clear identification.

Typical Applications

• Automotive control modules: Bulk decoupling and power smoothing in ECUs and control units where AEC‑Q200 qualification and −40 °C to 125 °C operation are required.
• DC‑DC converter outputs: Output filtering and energy storage for converters needing 150 µF capacitance, low ESR at low temperature, and defined ripple current handling.
• Telematics and sensor power: Local energy buffering for sensor front‑ends and telematics modules operating across wide temperature ranges.
• Power conditioning in harsh environments: Stabilizing rails and reducing noise in systems exposed to vibration and temperature stress, with compatibility for automated pick‑and‑place assembly.

Unique Advantages

• AEC‑Q200 Qualified Reliability: Qualification for automotive stress conditions supports use in safety‑critical and mission‑critical systems.
• Defined Low‑Temperature ESR: ESR specifications including post −40 °C test data reduce design risk for cold‑start and low‑temperature operation.
• Long High‑Temperature Endurance: 2000 hours at 125 °C gives clear life expectancy metrics for high‑temperature applications.
• Compact SMD Can: Small L: 7.7 × D: 6.3 mm package and standardized land pattern enable high‑density board layouts and automated assembly.
• Measured Ripple Performance: Specified ripple currents at both low and high frequencies allow designers to calculate lifecycle and thermal behavior precisely.
• RoHS Compliance: Meets RoHS directive requirements for regulated substances.
