DE37 Series
The DE37 Series has excellent surge response characteristics using micro gaps.
Useful informationFeatures
- The 5mm pitch; radial taped parts can be mounted using automatic insertion equipment (the part is lower than 15.5mm).
(except the item of over 2700V) - Also available in axial taping (the glass tube can be mounted flat using automatic insertion equipment).
- Can be used on megabit class high speed without attenuation of signal due a capacitance value of less than 1pF.
- Superior surge response characteristics due to microgap technology.
- High insulation resistance of over 100MΩ.
- Operating temperature limit : -40 ~ 85°C
- Storage Temperature Range : -55 ~ 125°C

Basic Conditions for ITU-T K.20
- Surge Test
10/700μs, 1.5kV/4kV (25Ω), 5 times.
- AC Induced Test
AC600V (600Ω), 1sec., 5 times.
- AC Cross Test
AC230V(10〜1000Ω), 15min.
(however, AC230 is too low for the DE37-401W to react)
