Overview
The Wurth Elektronik 7447789115 is a shielded SMD power choke coil designed for efficient energy storage and filtering in DC-DC converter circuits. Its ferrite core material and wirewound construction enable a nominal inductance of 15 µH, critical for stabilizing output voltage ripple. A key design consideration is the trade-off between inductance tolerance (±20%) and saturation current (1.75A); designers must carefully select operating points to avoid core saturation, which would drastically reduce effective inductance and compromise filtering performance, especially under transient load conditions. This AEC-Q200 qualified component offers robust operational stability within a wide temperature range.
Key Features
- Inductance: 15 µH (±20%)
- Maximum DC Current: 1.51 A
- Saturation Current: 1.75 A
- Maximum DC Resistance: 130 mOhms
- Operating Temperature Range: -40°C to +125°C
- Dimensions: 7.3 mm (L) x 3.2 mm (W) x 1.5 mm (H)
Applications
The component is engineered for deployment in systems requiring high reliability and performance under specific operating conditions. It provides functional stability across the stated design envelope.
- Buck/Boost converter output filtering
- Power sequencing for automotive infotainment systems
- EMI suppression in high-density power modules
- Energy storage in portable power management ICs
