F20J1R0E 数据手册

• All-welded construction.

• RoHS compliant product avail-

able. Add “E” suffix to part num-

ber to specify.

When limited space is a con-

sideration, choose Ohmite’s

“thin” stackable 250 Type

resistors. These oval-shaped

ceramic-core resistors feature

a low profile to permit instal-

lation in spaces with height

restrictions. They are also

equipped with integral mount-

ing brackets so they can be

fastened to a chassis and

stacked in locations with lim-

ited surface area.
