Newsletter-Autumn 2020 | High-End MELF SMD Resistors Manufacturer - FIRSTOHM

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. FIRSTOHM is one of the few companies who is able to design thin-film resistors according to customer's requirements with high quality and reliability. We’re specialized in MELF resistors since 1969, ISO9001/14001 certificated manufacturer.

SSWA - Superior Anti-Surge Wire Wound Axial Resistors

Application
  • ECG Leadwire
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)
  • Best quality and reliability for electrocardiogram (ECG Cable 3/5/10 leads) applications.
  • Low TCR against the other ceramic resistor.
  • Reduced total BOM cost with stable production lead time.

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.
