RKS1E151MCNAJJGS

The RKS1E151MCNAJJGS from Nichicon is a surface‑mount conductive‑polymer aluminum solid electrolytic capacitor in the RKS series, rated 150 µF at 25 V. Engineered for general‑purpose electronic designs, it delivers high capacitance in a compact, can‑style SMD package (φ10 × 10 mm) for power filtering and decoupling in systems that require low ESR and elevated ripple handling.

Key value propositions include low equivalent series resistance (20 mΩ at 100 kHz), high allowable ripple current (up to 2.0 A at high frequency), and long endurance (3000 hours at 125°C), making it suitable for demanding thermal and ripple environments.

Key Features

• Capacitance and Voltage — 150 µF nominal capacitance with a rated voltage of 25 V and capacitance tolerance of ±20% (at 120 Hz, 20°C).
• Conductive‑Polymer Construction — Solid polymer electrolyte for stable performance with low loss (tan δ 0.12 at 120 Hz, 20°C).
• Low ESR — 20 mΩ equivalent series resistance measured at 100 kHz and 20°C, supporting high‑frequency performance and reduced heat generation.
• High Ripple Current Capability — Low‑frequency ripple current 200 mA (120 Hz) and high‑frequency ripple current 2.0 A (300 kHz) for demanding power applications.
• Wide Temperature and Long Life — Operating range −55°C to +125°C with a rated load life of 3000 hours at 125°C.
• Leakage Current — Specified leakage current of 187 µA.
• SMD Can Package — Compact φ10 × 10 mm radial can-style SMD package, supplied in embossed carrier tape with moisture‑proof packing for automated assembly.
• Manufacturing and Reliability — SMD type designed for lead‑free reflow soldering with peak correspondence to 260°C and compliance to RoHS (per product series datasheet).

Typical Applications

• Power Supply Filtering — Bulk and output smoothing where high capacitance, low ESR and elevated ripple handling improve regulator stability and transient response.
• DC‑DC Converter Outputs — Local decoupling and energy buffering on converter outputs operating at high switching frequencies.
• Industrial and Communications Equipment — Power conditioning in systems that require wide operating temperature range and long operational life.

Unique Advantages

• Low ESR for Efficient Power Delivery: 20 mΩ at 100 kHz reduces losses and supports high‑frequency decoupling.
• High Ripple Tolerance: Rated for up to 2.0 A at high frequency, enabling use in high‑ripple and switching environments.
• Robust Thermal Endurance: 3000 hours at 125°C provides long operational life in elevated temperature conditions.
• Compact SMD Can Form Factor: φ10 × 10 mm package balances high capacitance with a small PCB footprint for space‑constrained designs.
• Assembly‑Ready Packaging: Supplied in embossed carrier taping with moisture‑proof packing to support automated surface‑mount assembly.
• RoHS‑Compliant Series: Series documentation indicates compliance with RoHS directives for environmental regulatory alignment.
