PCJ1C121MCL1GS

The PCJ1C121MCL1GS is a conductive polymer aluminum solid electrolytic chip capacitor in an SMD can package, designed for low ESR and higher capacitance in compact board-level applications. It combines a 120 µF capacitance with a 16 V rated voltage and an SMD form factor for space-efficient power conditioning.

Built for demanding environments, this capacitor offers low equivalent series resistance (24 mΩ at 100 kHz), high ripple-current capability, AEC-Q200 qualification, a rated operating range of −55 °C to +105 °C, and a 2000-hour load life at 105 °C. It is RoHS compliant and compatible with lead-free reflow soldering conditions up to a 260 °C peak.

Key Features

• Dielectric / Electrolyte — Conductive polymer aluminum solid electrolyte providing stable capacitance and low loss in a chip-type SMD construction.
• Capacitance & Voltage — 120 µF nominal capacitance with a 16 V rated voltage and ±20% tolerance at 120 Hz, 20 °C.
• Low ESR — ESR of 24 mΩ measured at 100 kHz, enabling improved high-frequency decoupling and reduced heat generation under ripple load.
• High Ripple Current — Rated ripple currents of 1.505 A at 120 Hz and 3.01 A at 100 kHz to support high-demand power rails.
• Robust Reliability — Load life specified as 2000 hours at 105 °C; endurance criteria include capacitance change within ±20%, tan δ and ESR ≤150% of initial values, and leakage current within initial limits after endurance testing.
• Automotive-Grade Qualification — AEC-Q200 qualified and specified for automotive applications with a temperature range of −55 °C to +105 °C.
• SMD Package & Assembly — Chip-type radial can SMD package (L: 7 × D: 8 mm) with recommended land size 8.3 × 8.3 mm; lead‑free reflow soldering condition compatibility at a 260 °C peak (single reflow at ≤260 °C).
• Regulatory — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive electronic modules — Suited for vehicle electronics that require AEC-Q200 qualification and extended temperature operation from −55 °C to +105 °C.
• Board-level power filtering — Low ESR and high ripple-current ratings make it suitable for decoupling and smoothing on compact power rails.
• High-ripple environments — Designed to handle elevated ripple currents (1.505 A at 120 Hz; 3.01 A at 100 kHz) in demanding in-vehicle power circuits.

Unique Advantages

• Low ESR for efficient high-frequency performance: 24 mΩ at 100 kHz reduces losses and improves transient response on power rails.
• High ripple-current capability: Specified ripple currents at both low and high frequencies support DC‑DC converters and switching power stages.
• Automotive-grade reliability: AEC-Q200 qualification and a 2000-hour load-life rating at 105 °C provide measurable endurance for vehicle systems.
• Wide operating temperature span: −55 °C to +105 °C supports harsh thermal environments common in automotive applications.
• SMD can in a compact footprint: 7 × 8 mm package size with a defined land pattern for dense PCBs and automated assembly workflows.
• Lead-free reflow compatible: Specified for lead-free reflow soldering up to a 260 °C peak, enabling modern assembly processes.
