Operating Temperature Range: -40

°C to +85°C

Only for reflow soldering.

<Allowable DC Current>

When Allowable DC Current is applied to the

Products, self-generation of heat will rise to

40

°C or less.

When Allowable DC Current is applied to the

Products, Inductance will be within +-30% of

nominal Inductance value.
