（一）Features：
Ⅰ.The SPER resistors are highly resistant to heat, compact, yet capable of withstanding high power. Additionally, these resistors are solid,
which means they provide superior frequency characteristics and high resistance to overloading.
Ⅱ.Furthermore, the SPER resistors can be used in water, which makes them ideal for use in high-frequency circuits and for other
applications that require a large current.
（二）Applications：
Ⅰ.Power supply circuits
Ⅱ.Dummy loads
Ⅲ.Circuits for protecting against parasitic oscillation
Ⅳ.PT protection
Ⅴ.High-frequency circuits
Ⅵ.Accelerators
Ⅶ.Other high-current circuits
Ⅷ.Ultrasonic devices
Ⅸ.Other applications: far-infrared heaters, microwave absorbers
（三）Power: 3W=3W,5W=5W,10W=10W,20W=20W,30W=30W,50W=50W
（四）Resistance: 0R100=1Ω,10R00=10Ω,100R000=100Ω,330R00=330Ω
（五）Resistance Tolerance: K=±10%
