GYF1E181MCQ1GS

The GYF1E181MCQ1GS from Nichicon is a conductive polymer hybrid aluminum electrolytic chip capacitor engineered for high-temperature, high-reliability applications. It combines low ESR and high ripple-current capability with a compact surface-mount can package suited for space-constrained assemblies.

Designed for demanding automotive and battery-management applications, the GYF1E181MCQ1GS delivers 180 µF at 25 V with a rated temperature range of −55 °C to 125 °C and a guaranteed lifetime of 4000 hours at 125 °C.

Key Features

• Capacitance & Voltage — 180 µF rated capacitance at 25 V with ±20% tolerance (measured at 120 Hz, 20 °C).
• Conductive Polymer Hybrid — Hybrid construction for reduced ESR and improved ripple handling compared to conventional electrolytics.
• Low ESR — Equivalent Series Resistance of 30 mΩ at 100 kHz, 20 °C for improved power delivery and reduced loss in high-frequency circuits.
• High Ripple Current — Supports 270 mA at 120 Hz and 1.8 A at 100 kHz, enabling robust performance in high-ripple environments.
• High-Temperature Endurance — Rated endurance of 4000 hours at 125 °C with specified limits on capacitance, tan δ and ESR after test.
• Wide Operating Range — Specified for −55 °C to 125 °C operation and demonstrated impedance stability (Z(−25 °C)/Z(+20 °C) ≤ 2; Z(−55 °C)/Z(+20 °C) ≤ 2.5 at 100 kHz).
• Automotive-Grade Qualification — AEC-Q200 qualified to support automotive system requirements.
• Surface-Mount Can Package — Radial SMD can with compact dimensions L: 7.7 × D: 6.3 mm and recommended land size L: 6.6 × W: 6.6 mm for PCB integration.
• RoHS Compliance — Compliant with RoHS directive (2011/65/EU and (EU)2015/863).

Typical Applications

• Battery Management Systems (BMS): High ripple tolerance and long 125 °C lifetime make this capacitor suitable for filtering and energy buffering in BMS modules.
• Automotive Electronic Modules: AEC-Q200 qualification and wide temperature range support use in automotive control modules and power electronics.
• High-Ripple Power Circuits: Low ESR and specified high-frequency ripple current capacity enable use in power-supply filters and DC link applications where ripple handling is critical.

Unique Advantages

• Long High-Temperature Life: 4000 hours at 125 °C rated endurance for prolonged reliability in hot environments.
• Improved Power Efficiency: 30 mΩ ESR at 100 kHz reduces power loss and heat generation in high-frequency circuits.
• High Ripple Capability: Specified ripple currents at 120 Hz and 100 kHz address both low- and high-frequency ripple demands.
• Automotive-Ready: AEC-Q200 qualification supports integration into automotive electronic systems requiring industry-recognized component validation.
• Compact SMD Can: Small footprint (7.7 × 6.3 mm) and surface-mount land pattern simplify placement in dense PCB layouts.
• Stable Performance Across Temperature: Tight impedance ratios across −55 °C to +20 °C ensure predictable filtering behavior over the operating range.
