PCV1E121MCL1GS

The PCV1E121MCL1GS is a surface-mount, conductive polymer aluminum solid electrolytic capacitor in Nichicon’s PCV series. It delivers 120 µF capacitance at a 25 V rating in a compact chip-style can (φ10 × 8 mm), optimized for applications that require low ESR and high ripple-handling in demanding temperature environments.

Engineered for long life and robust thermal performance, this part is AEC‑Q200 qualified and rated for operation from -55 °C to +105 °C, with a load life of 3000 hours at 105 °C—making it suitable for automotive power applications where stability and durability are required.

Key Features

• Capacitance & Voltage — 120 µF nominal capacitance with a rated voltage of 25 V and tolerance ±20%.
• Low Equivalent Series Resistance (ESR) — ESR of 35 mΩ measured at 100 kHz, 20 °C, enabling efficient high-frequency decoupling and lower power dissipation.
• High Ripple Current Capability — Low-frequency ripple current 900 mA (120 Hz) and high-frequency ripple current 1.8 A (100 kHz) to support switching regulators and power rails.
• Leakage & Loss Characteristics — Leakage current specified at 600 µA and tan δ (DF) of 0.12 at 20 °C, 120 Hz for predictable loss behavior.
• Long Life & Endurance — Rated for 3000 hours at 105 °C; endurance criteria include capacitance within ±20%, tan δ and ESR within 150% of initial values, and leakage current not exceeding initial values after test.
• Automotive-Grade Qualification — AEC‑Q200 qualified and designed for a -55 °C to +105 °C operating range.
• Surface-Mount, PCB-Ready Package — Chip-type radial can SMD package (φ10 × 8 mm) supplied in embossed carrier taping with moisture-proof packing for automated assembly.
• RoHS Compliant — Conforms to RoHS directive requirements.
• Reflow Soldering Compatibility — Compatible with lead-free reflow profiles: peak soldering conditions up to 260 °C (single reflow at ≤260 °C, or up to 250 °C for two reflows) when following recommended soldering profiles.

Typical Applications

• Automotive ECUs and Power Modules — Provides low-ESR bulk and decoupling capacitance for power rails and DC‑DC converters in electronic control units, benefiting from AEC‑Q200 qualification and wide temperature range.
• On‑Board Power Conditioning — Supports switch‑mode power supply filtering and high-frequency ripple suppression thanks to 35 mΩ ESR and 1.8 A high-frequency ripple capability.
• Infotainment and Body Electronics — Improves transient response and reduces voltage ripple in infotainment power domains and body-control modules where long life and stable performance at elevated temperatures are required.

Unique Advantages

• Automotive-Ready Reliability: AEC‑Q200 qualification plus a -55 °C to +105 °C rating and 3000 h life at 105 °C support deployment in vehicle electronics.
• High Ripple Acceptance: Specified low- and high-frequency ripple currents (900 mA @120 Hz, 1.8 A @100 kHz) reduce the need for parallel capacitors in many power designs.
• Low ESR for Efficient Power Delivery: 35 mΩ ESR at 100 kHz minimizes losses and improves regulator stability and thermal performance.
• Compact SMD Form Factor: φ10 × 8 mm chip-style can in embossed carrier tape simplifies automated placement while saving board space compared with larger through-hole options.
• Predictable Endurance: Endurance and damp-heat specifications define measurable limits for capacitance, tan δ, ESR and leakage after extended stress, aiding reliability planning.
• Manufacturing-Friendly: Compatible with lead-free reflow profiles and supplied in moisture-proof, embossed tape packaging to support standard SMT assembly flows.
