extent, the sales manager is going to reconfirm the order and let you know if there
are any updates.
Shipping starts at $40, but some countries will exceed $40. For
example (South Africa, Brazil, India, Pakistan, Israel, etc.)
The
basic freight (for package ≤0.5kg or corresponding volume) depends on the time zone and
country.
Currently, our products are shipped through DHL, FedEx, SF, and UPS.
Delivery TimeOnce the goods are shipped, estimated delivery time depends on the shipping methods you chose:

LM2917N Description
The LM2917N is a monolithic frequency-to-voltage converter with a high gain op-amp designed to operate a relay, lamp, or another load when the input frequency reaches or exceeds a selected rate. The tachometer uses a charge pump technique and offers frequency doubling for low-ripple, full-input protection in two versions (8-pin LM2907 and LM2917), and its output swings to the ground for a zero frequency input.
The LM2917N is fully compatible with the tachometer and has a floating transistor as its output. This feature allows either a ground or supply referred load of up to 50 mA. The collector may be taken above VCC up to a maximum VCE of 28 V.
LM2917N Features
Ground Referenced Tachometer Input Interfaces Directly With Variable Reluctance Magnetic Pickups
Op Amp Has Floating Transistor Output
50-mA Sink or Source to Operate Relays, Solenoids, Meters, or LEDs
Frequency Doubling For Low Ripple
Tachometer Has Built-In Hysteresis With Either Differential Input or Ground Referenced Input
+0.3% Linearity (Typical)
Ground-Referenced Tachometer is Fully Protected From Damage Due to Swings Above Vcc and Below Ground
