101
TYPE 8RHB
Inductance Range:
1.0-1000µH
Temperature Coefficient:
400ppm/°C, max.
Features
• Ideal as a choke coil for noise filtering and DC/DC
convertor applications.
Note: Taped form is Type 8RHT (see complete specification on page 102).
STANDARD PARTS SELECTION GUIDE
(1) Q and Inductance are measured by Q meter YHP-4343B or
equivalent.
(2) The rated DC current is that which the inductance value
decreases 10% by the excitation DC current, measured
at 1KHz by Precision LCR meter 4284A (hp) or equivalent.
(3) The rated DC current which the part temperature rises 20°C
by the excitation DC current from room temperature (20°).
(4) SRF is measured by Network Analyzer 3577A (hp), MS560J
(Anritsu) or equivalent.
(5) DC Resistance is measured by Digital Multimeter TR6871
(Advantest) or equivalent.
(6) SRF is for reference only.
