RKS1J470MCNAHHGS

The RKS1J470MCNAHHGS is a conductive-polymer aluminum solid electrolytic capacitor in a surface-mount radial-can package. It provides 47 µF capacitance at a 63 V rating with a capacitance tolerance of −20% to +20% and is optimized for applications requiring low ESR, high allowable ripple current and extended high-temperature operation.

Designed for SMD assembly and long-term reliability, this capacitor features a rated operating range to 125 °C, a load life of 3000 hours at 125 °C, and compatibility with reflow soldering profiles up to a 260 °C peak.

Key Features

• Conductive-polymer aluminum construction — Solid electrolytic chemistry for stable performance and reduced losses compared with traditional wet electrolytes.
• Capacitance & tolerance — 47 µF nominal capacitance with −20%/+20% tolerance at 120 Hz, 20 °C.
• Voltage rating & polarization — Rated at 63 V; polarized device intended for DC applications.
• Low loss characteristics — tan δ = 0.12 (measured at 20 °C, 120 Hz) for controlled dissipation in AC conditions.
• Low ESR and high ripple capability — ESR 40 mΩ at 20 °C/100 kHz; ripple current ratings of 110 mA at 120 Hz and 1.1 A at 300 kHz.
• Leakage current — Measured leakage current 148 µA (specified per datasheet conditioning and measurement conditions).
• Extended high-temperature life — Endurance rated for 3000 hours at 125 °C under rated voltage.
• Package & footprint — Radial can SMD package, size φ8 × 8.7 mm length; recommended land size 8.3 × 8.3 mm. Supplied in embossed carrier tape with moisture-proof packing for automated placement.
• Reflow compatibility — Compatible with lead-free reflow soldering conditions, measurement based on peak temperature up to 260 °C as specified in the datasheet.
• RoHS compliance — The series is stated as compliant to the RoHS directive in the datasheet.

Typical Applications

• High-frequency power stages — Low ESR (40 mΩ at 100 kHz) and 1.1 A ripple rating at 300 kHz make this capacitor suitable for decoupling and filtering in high-frequency DC–DC converter outputs.
• Bulk decoupling in high-temperature equipment — Rated for operation to 125 °C with a 3000-hour load life at 125 °C, enabling use where elevated ambient temperatures are expected.
• SMD power modules — Radial can SMD package and embossed carrier taping simplify automated assembly for compact power module designs.
• Low-loss filtering — Low tan δ and controlled leakage current support applications where AC loss and standby leakage must be managed.

Unique Advantages

• Low ESR for improved filtering: 40 mΩ ESR at 100 kHz reduces voltage ripple and heat generation in high-frequency circuits.
• High allowable ripple current: 1.1 A at 300 kHz (high-frequency) and 110 mA at 120 Hz (low-frequency) support demanding power applications.
• High-temperature endurance: 3000-hour rated life at 125 °C provides predictable long-term performance in elevated-temperature environments.
• Reflow-ready SMD can: Designed for lead-free reflow soldering up to 260 °C peak, enabling standard surface-mount assembly flows.
• Compact footprint with SMD supply: φ8 × 8.7 mm size and embossed carrier taping support automated placement while conserving board area.
• Controlled dissipation and leakage: Specified tan δ (0.12) and measured leakage current (148 µA) allow designers to model losses and standby behavior accurately.
