Frequently Asked Questions
What inductance value does the SRR1208-103KL provide and how does it affect filtering performance?
The SRR1208-103KL provides a nominal inductance of 10000 µH, which delivers high impedance at lower frequencies and is effective for attenuating switching noise in power supplies operating below 1 MHz. This high inductance value makes it suitable for general-purpose power line filtering where deep attenuation over a wide frequency range is required.
What is the DC resistance of the SRR1208-103KL and how does it impact power efficiency?
The SRR1208-103KL has a DC resistance (DCR) of 19.2 Ω, which contributes to I²R power losses in the circuit. Designers should account for this resistance when calculating efficiency in low-current filtering applications, ensuring that the inductor's current rating aligns with the circuit requirements to avoid excessive heating.
Which package does the SRR1208-103KL use and what are its physical dimensions?
The SRR1208-103KL uses a 5050 molded rectangular package, which measures approximately 12 mm × 8 mm footprint. This compact form factor allows integration into space-constrained PCB designs while providing the mechanical durability needed for automated pick-and-place assembly in high-volume production environments.
Is the SRR1208-103KL RoHS-compliant and lead-free for use in environmentally regulated products?
Yes, the SRR1208-103KL is marked as Pb-free and RoHS-compliant, making it suitable for use in products subject to EU RoHS Directive and similar environmental regulations. The component supports lead-free soldering profiles up to 260°C peak reflow temperature as required for modern SMT assembly processes.
