NOTE
*Actual body length is shorter. However, due to epoxy
coating, sometimes we do have a very thin layer extended
on leads, we have to use .03" tolerance to cover this area.
**We can also provide smaller part with OD 0.147"+/0.02 with same electrical charteristics as our standard
parts. Please consult factory for this item.
