Superior Anti-Surge Wire Wound Axial Resistors Reduced Total Bom Cost with Stable Production Lead Time
It is not far-fetched to say that the COVID-19 outbreak has been a global health crisis and the biggest challenge we had to face in 2020. During this pandemic, the demand of personal respiratory protective devices and other medical devices increased rapidly, which leads to a shortage of some key components.
Now, FIRSTOHM has released a new product (SSWA series) dedicated to ECG cable applications with safety, quality and reliability.
SSWA - Superior Anti-Surge Wire Wound Axial Resistors
Features
● Special composite wire-wound structure enhances anti-surge capability. “Patent pending”
● Rated to withstand the defibrillation pulse tests described in ANSI/AAMI/IEC 60601-2-27
● Rated to withstand the ESD pulse tests described in IEC 61000-4-2
(Including both 8kV contact discharge and 15kV air discharge)
● Optimal quality and reliability for electrocardiogram (ECG) monitor (3/5/10 leads) applications.
● Reduced total BOM cost with stable production lead time.
● Low T.C.R against the other ceramic resistors.
ECG cable acts as a necessary route between human body and ECG machine, there are two reasons to add a resistor inside the wire of ECG cable :
1. To avoid EMI/RFI between each party.
2. For safety to limit any current to the patient in case of some sort of equipment failure.
The protection component(SSWA) must have sufficient capability to stand energy of defibrillator pulses but also to stand possible ESD pulses without specification degradation while maintaining high reliability during the lifetime of the components.
