SRN4018TA-3R3M is a semi-shielded power inductor from Bourns' SRN4018TA series, featuring a nominal inductance of 3.3 µH at 100 kHz with ±20% tolerance. The inductor is rated for 2.3 A RMS continuous current with a saturation current of 2.3 A, and exhibits a DC resistance of 0.055 O (±20%) with a self-resonant frequency of 60 MHz. Operating across a temperature range of -55°C to +125°C with a 40°C temperature rise at rated current, this component is AEC-Q200 qualified and RoHS compliant with halogen-free construction. The semi-shielded design and compact form factor make it ideal for power supply filtering, DC-DC converter applications, and other compact power management circuits where space and thermal performance are critical.
