RKS1D151MCNAHHGS

The RKS1D151MCNAHHGS is a surface-mount conductive polymer aluminum electrolytic capacitor from Nichicon's RKS series. It delivers 150 µF at 20 V with low equivalent series resistance and high allowable ripple current in a compact φ8 × 8.7 mm SMD can package.

Designed for high-temperature and high-ripple environments, this part offers a wide operating temperature range of −55°C to +125°C and a rated lifetime of 3000 hours at 125°C, making it suitable for demanding power and industrial electronics applications where stability and endurance matter.

Key Features

• Electrical Performance — 150 µF nominal capacitance with ±20% tolerance and tanδ of 0.12 (20°C, 120 Hz) for predictable AC behavior.
• Low Impedance & High Ripple Handling — ESR of 30 mΩ at 20°C/100 kHz and high-frequency ripple current rating of 1.6 A (300 kHz) enable effective smoothing and decoupling in high-frequency power circuits; low-frequency ripple rated at 160 mA (120 Hz).
• High-Temperature Endurance — Rated for −55°C to +125°C with a load-life specification of 3000 hours at 125°C, supporting long-term operation in elevated-temperature environments.
• Leakage and Reliability — Leakage current specified at 150 µA; endurance tests specify limits on capacitance change, tanδ and ESR after 3000 hours at rated voltage and 125°C.
• Surface-Mount Can Package — Radial can SMD package (φ8 × 8.7 mm), supplied in embossed carrier taping with moisture-proof packing and compatible with lead‑free reflow up to a 260°C peak soldering profile.
• RoHS Compliant — Manufactured to meet RoHS directive requirements.

Typical Applications

• Power supply filtering and smoothing — Low ESR and high ripple-current capability help stabilize DC outputs and reduce voltage ripple in DC‑DC converters and power rails.
• High-frequency power modules — 1.6 A ripple current rating at 300 kHz and low impedance support decoupling in switching power stages and power-management modules.
• Industrial and embedded electronics — Extended temperature range (−55°C to +125°C) and 3000 h life at 125°C provide durability for industrial controllers and embedded systems operating in harsh conditions.
• Telecom and networking equipment — Compact SMD can package with high endurance is suited for board-level bulk capacitance and hold-up requirements in telecom power circuitry.

Unique Advantages

• High-temperature reliability: 3000 hours at 125°C endurance rating supports long operational life under elevated thermal stress.
• High ripple tolerance with low ESR: 30 mΩ ESR at 100 kHz and 1.6 A high-frequency ripple current enable efficient high-frequency decoupling and reduced heat generation.
• Compact surface-mount form factor: φ8 × 8.7 mm can-style SMD package delivers substantial capacitance while minimizing board footprint.
• Reflow-assembly ready: Compatible with lead-free reflow up to 260°C peak, supporting modern SMT assembly processes.
• Predictable leakage and loss characteristics: Specified leakage current (150 µA) and tanδ (0.12) provide measurable parameters for power‑budgeting and stability analyses.
