The SRR1210-270M is a shielded SMD power inductor from Bourns designed for input/output filtering in DC/DC converters and power supply applications. It features a 27 µH inductance with ±20% tolerance, a self-resonant frequency of 6.5 MHz, and a maximum DC resistance of 5.0 mO. The inductor is rated for 4.2 A RMS continuous current with a saturation current of 15 A, and operates reliably over a temperature range of -40°C to +125°C with a typical temperature rise of 40°C at rated current. Its compact 10 mm height and shielded design make it ideal for portable communication equipment, camcorders, LCD TVs, and other space-constrained power management applications requiring efficient energy storage and filtering.
