The **MHO+41TAG-R** is a high-performance, surface-mount (SMD) clock oscillator manufactured by **MtronPTI**. It belongs to the MHO+ series, which is known for providing stable timing references in a compact package. --- ### 1. Technical Specifications The following table highlights the primary electrical characteristics of the MHO+41TAG-R: | Parameter | Specification | | :--- | :--- | | **Output Type** | HCMOS / TTL Compatible | | **Supply Voltage (Vcc)** | 5.0 Volts (Nominal) | | **Frequency Stability** | ±100 ppm (Typical for this series) | | **Operating Temperature** | -40°C to +85°C (Industrial Grade) | | **Package Type** | 4-Pad Ceramic SMD | | **RoHS Status** | Compliant (Lead-Free) | --- ### 2. Part Number Breakdown To understand the specific features of this component, we can look at the nomenclature used by MtronPTI: * **MHO+**: Product series (HCMOS/TTL Clock Oscillator). * **4**: Indicates the voltage (5.0V). * **1**: Denotes the frequency stability (often ±100ppm depending on the specific datasheet revision). * **T**: Specifies the operating temperature range (Industrial: -40°C to +85°C). * **A**: Tri-state enable/disable function on Pad 1. * **G**: Symmetry/Duty Cycle requirements (typically 40/60% or 45/55%). * **R**: Indicates RoHS compliance. --- ### 3. Pin Configuration The device features a standard 4-pad layout common to SMD oscillators: 1. **Pad 1: Tri-state (Enable/Disable).** High or Floating = Output active; Low = High impedance. 2. **Pad 2: Ground (GND).** Connection to the negative supply rail. 3. **Pad 3: Output.** The high-speed clock signal. 4. **Pad 4: Vcc.** Positive supply voltage (+5V). --- ### 4. Key Applications Because of its 5V operation and industrial temperature rating, it is commonly found in: * **Embedded Systems:** Providing the master clock for microcontrollers. * **Telecommunications:** Timing for network interface cards. * **Industrial Controls:** Used in PLCs and rugged automation hardware. * **Legacy Hardware:** Supporting older TTL-logic based circuits that require 5V levels.
