RKS1J270MCNAHJGS

The RKS1J270MCNAHJGS is a surface-mount conductive polymer aluminum solid electrolytic capacitor with a nominal capacitance of 27 µF and a rated voltage of 63 V. It is designed for general-purpose power and decoupling applications that require low ESR, high allowable ripple current, and extended high-temperature endurance.

Key value propositions include low equivalent series resistance (40 mΩ at 100 kHz), high-frequency ripple capability (1.1 A at 300 kHz), and a rugged operating temperature range from −55 °C to 125 °C with a rated life of 3000 hours at 125 °C.

Key Features

• Dielectric and Construction — Conductive polymer aluminum solid electrolytic construction for stable performance and low loss.
• Capacitance & Tolerance — 27 µF nominal capacitance with tolerance of −20% to +20% at 20 °C, 120 Hz.
• Rated Voltage — 63 V rated voltage suitable for a wide range of mid-voltage power rails and DC bus applications.
• Low ESR — ESR of 40 mΩ measured at 20 °C and 100 kHz, supporting high-frequency decoupling and fast transient response.
• High Ripple Current — Low-frequency ripple current 110 mA (120 Hz) and high-frequency ripple current 1.1 A (300 kHz) for demanding power applications.
• Leakage and Loss — Leakage current specified at 100 µA and tan δ (loss tangent) of 0.12 at 20 °C, 120 Hz.
• Thermal and Endurance — Operating temperature −55 °C to 125 °C with load life of 3000 hours at 125 °C.
• Surface-Mount Package & Packaging — Radial can SMD package (φ8 × 10L) supplied in embossed carrier taping with moisture-proof packing for automated assembly.
• Compliance — RoHS compliant.
• Reflow-Compatible — Designed for lead-free reflow soldering per series guidelines (peak 260 °C) as noted in manufacturer documentation.

Typical Applications

• Power Supply Decoupling — Provides low-ESR bulk decoupling on mid-voltage rails to reduce voltage ripple and improve regulator stability.
• DC-DC Converters — Handles high-frequency ripple and transient currents in switching converter outputs and intermediate bus capacitors.
• Power Modules & Power Management — Suited for local energy storage and filtering in power modules where compact SMD packaging and thermal endurance are required.
• General Purpose Electronics — Useful across industrial and commercial equipment for smoothing, filtering, and transient suppression within the specified voltage and temperature ranges.

Unique Advantages

• High-Frequency Performance: Low ESR (40 mΩ at 100 kHz) and 1.1 A high-frequency ripple rating enable effective suppression of switching noise and improved transient response.
• Extended High-Temperature Endurance: 3000-hour life at 125 °C supports reliability in thermally demanding designs and long-term operation at elevated temperatures.
• Compact SMD Form Factor: Radial can SMD package in embossed carrier taping simplifies automated placement while delivering high capacitance in a small footprint.
• Low Loss and Controlled Leakage: tan δ of 0.12 and leakage current of 100 µA provide predictable loss characteristics and low standby current for power-sensitive designs.
• RoHS Compliance: Environmentally compliant material selection supports regulatory needs without compromising electrical performance.
• Manufacturing-Ready Packaging: Supplied in moisture-proof taped packaging to support standard pick-and-place and reflow assembly processes.
